This is a Qemu error. Typically, the firmware binary is part of the
Qemu package. I have some questions that help to narrow down the cause
of the error.

- Which version of Qemu is used?
- Does you Qemu package contain the file opensbi-riscv64-virt-fw_jump.bin?
  find <path to package> -name opensbi-riscv64-virt-fw_jump.bin
- Do you use Qemu from your Linux distribution or did you build it
  manually?
- If manually built, which configuration did you choose when building?
